This report presents the results of a study that was undertaken to identify student attitudes toward the Pass-Fail (P-F) option at the University of Washington. A questionnaire designed to assess student opinions toward and possible behavioral changes resulting from P-F courses was sent to a random sample of sophomores, juniors and seniors enrolled in the Spring of 1969 who had originally entered the University before the Fall of 1968. Of 6,700 questionnaires distributed, 3,400 useable ones were returned. The major findings were: (1) the vast majority of students want the P-F option continued; (2) most students would have taken P-F courses for regular grades (R-G) had the P-F option not existed; (3) most P-F courses are taken for the relief they afford from grading pressure; (4) most students reported working less hard in P-F courses than in R-G courses; (5) roughly two-thirds of the students had not taken P-F courses in the Spring of 1969; and (6) roughly two-thirds of the students at the University will have taken P-F courses before graduation.
